Special features
Standard with surge counter
Two-module design in the Max series delivers 400 kA per phase, providing robust defense for sensitive drives, PLCs, and automation panels in 120/208 V Wye systems. Business impact: dramatically reduces the risk of downstream equipment damage and unplanned downtime, enabling smoother production throughput and lower maintenance costs in mid-size to large industrial facilities. Application: ideal for control cabinets, machine centers, and distributed power panels where compact protection is needed without sacrificing performance. The enclosure is a rugged NEMA 4X with an internal terminal block, simplifying installation and wiring in harsh environments. This translates to faster commissioning, fewer field wiring errors, and better weather resistance on plant floors or outdoor installations. The device comes standard with a surge counter, enabling straightforward condition monitoring and proactive maintenance planning, which improves uptime and extends asset life in automation networks. Compatibility with RoHS requirements ensures sustainability across modern electrical assemblies and supplier compliance programs, while the 15‑year warranty (20 years with Eaton registration) supports long‑term ownership and total cost of ownership considerations. Measured benefits include improved protection for 120/208 V systems, predictable service intervals, and reduced replacement cycles for surge-sensitive equipment, making this SPD MAX a trusted choice for mission-critical automation environments. Weight and dimensions—50 lb, 9.3 in depth, 17.5 in height, 14.91 in width—support fitment in standard electrical spaces and enable straightforward mounting in existing racks and enclosures, minimizing retrofit costs and permitting quick upgrades to legacy protection schemes.

FAQs
For optimal results, mount the unit in a compliant enclosure with adequate clearance for the 9.3 in depth, 14.91 in width, and 17.5 in height footprint. Wire it to a suitable mains source via the internal terminal block, and ensure proper grounding and overcurrent protection. The two-module design fits compact control cabinets without sacrificing surge capability, simplifying field installation and future expansions.
SPM400208Y3Y provides 400 kA per phase protection for 120/208 V Wye systems (4W+G). It uses a two-module configuration in the Max series and includes a surge counter. The unit is RoHS compliant and supports standard OSHA/industry protection requirements while delivering reliable, scalable surge protection for automation panels and critical loads.
Yes. The device is installed in a NEMA 4X enclosure, which offers excellent protection against dust, water, and corrosion in demanding environments. The internal terminal block simplifies wiring in rugged settings, and the RoHS compliance ensures reduced environmental impact—making it well-suited for factory floors, outdoor installations, and harsh industrial spaces.
The SPM400208Y3Y is UL 1449 and UL 1283 listed, and CSA listed (CSA Std. C22.2 No. 8-M1986) with CSA Electrical Notice NO. 516 Edition 1. These certifications validate compliance for North American electrical installations and provide confidence in safety and performance for mission-critical protection.
The built‑in surge counter enables proactive maintenance, reducing unplanned downtime by signaling when protection performance warrants attention. Paired with a 15‑year warranty (20 years with registration), this SPD MAX lowers total cost of ownership by extending asset life, minimizing downtime, and decreasing replacement frequency for surge‑damaged components in 120/208 V automation systems.
